On 1st August 2025, I found myself standing on the production floor at Atlantis Tanks’ Mildenhall facility, watching a small crowd gather for the unveiling of something the company says will reaffirm its position as “an indispensable supplier of liquid storage solutions” by putting power in the hands of customers. From what I saw, I believe them.
After 18 months of research and development, and with installer feedback at the heart of their efforts, Atlantis has launched a completely reimagined range of steel tanks – starting with nine bunded oil tanks. It’s not just a product refresh either, it’s a whole new way of thinking about liquid storage, powered by what they’ve christened Imperium® Technology. The name, as I discovered chatting to the team who chose it from a long list of possibilities, comes from the Latin for “power and control” – and it’s a fitting choice.
“It’s about innovation,” Managing Director Jon Mytton told me. “Going the extra mile in everything and collaborating to succeed.”
The heart of this innovation is the modular design. As Sales Director Kieran Mytton explained: “The tank bodies are core products with fittings plates that are removable and interchangeable. That makes it easy to offer multiple use cases and makes switching simple.”
This “core model” approach means Atlantis can standardise production without sacrificing versatility. The same tank shell can serve as a heating oil tank today, a waste oil container tomorrow, or even a diesel feed tank for a generator – simply by swapping the top fittings plate. That plate, by the way, comes off in just a couple of minutes, as demonstrated on the day by Kieran himself.
“Weld quality is everything,” Jon stressed. “Every millimetre of weld is tested.”
They’ve also reduced weak points by using folds instead of welded joints wherever possible. No surprise then that Atlantis offers a 10-year warranty they “are extremely confident will not be needed”. Given that they’ve made 15–18,000 tanks since moving to the Suffolk area in 2019, and had fewer than 10 warranty claims, that confidence seems justified.
From an installer’s perspective, several features stand out:
The steel is mild steel – cold-rolled. Every tank built on site in Suffolk and can be delivered direct to site on their own HIAB trucks or via pallet delivery.
Thanks to the leaner, more efficient production process, lead times are being reduced. And because the tanks are based on core models with market-specific fittings, Atlantis can switch production lines quickly as demand changes. This is a big win for installers who want reliable delivery dates.
Heating oil remains Atlantis’ mainstay – and will be for some time, despite the government’s boiler ban and push towards electrification. But they’re also looking ahead.
“We have further rollouts planned for power generation, agriculture, construction and automotive,” Kieran told me.
That diversification makes sense. The need for resilient standby power, for example, is growing. As Jon reminded us, when Heathrow suffered a major outage, the financial and operational costs were huge. Tanks like these make a vital difference to businesses dependent on a reliable power supply.
The launch itself was as practical as it was celebratory. With guests and the Atlantis team assembled, Guest of Honour Stuart Bratt, CEO of Ultra Compact Ltd, dropped the curtain to unveil two of the new tanks: a grey generator feed tank fitted with feed and return, bund alarm and high-level alarm; and a green heating oil tank. Both share the same Imperium® design, and both can be transformed for other uses in minutes.
Stuart summed it up neatly: “It’s ticking the boxes for the installer, for the end user, and for the manufacturing process as well.”
The first nine heating oil models are available to pre-order now, with deliveries starting 1st September 2025. They’ll run alongside Atlantis’ existing range for a while, so installers can try them at their own pace before the full transition.
Leaving the excellent launch, I was struck by how much thought Atlantis has put into the needs of installers – from customer satisfaction, through ease of maintenance to future-proof adaptability. These tanks are more than just steel boxes to hold fuel; they’re designed to be part of a longer-term, flexible solution.
And for a sector facing change, uncertainty, and opportunity all at once, that could be exactly what is needed.
